Consistency and accuracy in training lead to better results, which is why using a consistently accurate and reliable power meter is vital. Quarq power meters using Quarq technology, measure power at the crankset spider. This the best place on the bike to measure power because all of your pedaling effort flows directly through the spider and it can be measured with great precision. Quarq's Active Temperature Compensation, which is calibrated with over 10,000 data points, makes their ELSA RS Power Meter Crankset accurate to within 1.5% (strain gauges benefit from accurate temperature). Plus the ELSA RS is specifically designed to match Shimano's 4-bolt Hollowglide chainrings for a seamless junction between ring and chassis. Quarq's Exogram Hollow Carbon crankarms deliver every watt to the road while keeping the weight incredibly low. ANT+ technology lets you hook up your desired compatible head unit, the LED indicator flashes when the power meter is on, and the single, easily-replaced CR2032 battery lasts for up to 300 hours of ride time.
- Compatible with 11-speed Shimano chainrings (Dura-Ace, Ultegra, and 105)
- Chainrings and bottom bracket are sold separately
- Requires ANT+ head unit (sold separately)
- 616 grams (GXP, 172.5mm)

Pioneer's full crankset power meters are simply some of the best power-monitoring systems on the planet, and Pioneer's Shimano Ultegra 6800 crankset is your chance to ride the same technology used by the world's best riders. Pioneer's created the first, and only, power meter that measures power output and pedaling stroke efficiency for each individual leg, in real time, so you can analyze and adjust your technique on the fly. At the heart of Pioneer's Power Meter System are two streamlined strain gauge monitors that can detect the slightest tangent and radial force direction as power's applied to the crank arms. This proprietary system detects the amount and direction of force at 12 different points in each pedaling stroke for each leg, allowing you to fine-tune your pedaling to find race-winning form. With advanced technology accurate to +/- 2%, ANT+ transmitting, active temperature compensation, Pioneer's power meter is perfect for any cyclist. Additionally, installation is fast, simple, and clean with zero wires, magnets, or zip ties.

The SRAM RED AXS power meter breaks with tradition — and breaks through to new levels of performance. SRAM reengineered road gearing: reducing front chainring size and adding more range to the rear cassette. They also maintained a 13-tooth delta on all chainring pairs, ensuring precise shifting for any setup. This results in more useful gearing and better shifting across all configurations. These power meters are also designed with Quarq's premier DZero power measurement technology fully integrated into the crankset. Welcome to the pinnacle of the power meter.
